A new report from the MIT Joint Program on the Science and Policy of Global Change shows the importance of all major nations taking part in global efforts to reduce emissions—and in particular, finds China’s role to be crucial. From 2000 to 2010, China’s energy use grew 130%, up from a growth of 50% the previous decade.

It makes an important contribution to the scientific understanding we have of the role of aviation for climatechange—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement. This new study is based on a thorough review of a decade of research on aviation emissions.
Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climatechanges, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.
Global accounting firm PricewaterhouseCoopers has analyzed carbon emissions from 2000 to 2008 and concluded that the world’s “carbon emissions budget”, or ability to emit carbon dioxide while still maintaining a “fair chance” of limiting average global temperatures to no more than 2 ºC (3.6 Click to enlarge.

Global leaders agreed a target of limiting temperature increase to 2 °C at the UN climatechange talks in Cancun in 2010. These latest estimates from the IEA are “ a stark warning ” to governments to provide strong new progress this year towards global solutions to climatechange, UN Climate Chief Christiana Figueres said.
Anthropogenic global greenhouse gas emissions increased by 15% between 2000 and 2005, a sharp increase in the expected rate of growth, according to a new report from the European Commission’s Joint Research Centre (JRC).
The SMP model calculates 2000?2050 The Ford team updated the SMP model with historical data for 2000, 2005, and 2010, and extended the model to calculate the total CO 2 emissions (tonnes) and the TTW (tank-to-wheel) emission rate (g CO 2 /km) for the new vehicle fleet. They converted from an absolute amount to scale relative to 2000.
W m -2 relative to 2000. This increase may be as much as one-fifth to one-quarter of the expected increase in radiative forcing due to the buildup of CO 2 since 2000, according to the SRES emission scenarios. Climate and the Ozone Layer. By 2050, the buildup of HFCs is projected to increase radiative forcing by up to 0.4
The researchers first calculated the historic contributions from transport, concluding that transport in total has contributed 9% of total net man-made warming in the year 2000. By sector, they found that road transport is the largest contributor—11% of the warming in 2000 is due to this sector. Aviation contributed 4% and rail 1%.
The authors analyzed measurements from several independent sources—satellites and several types of ground instruments—and found a definitive increase in stratospheric aerosol since 2000. The increase in aerosols since 2000 implies a cooling effect of about 0.1 watts per square meter—enough to offset some of the 0.28

Our results suggest that gas-aerosol interactions play an important role in methane’s GWP, and hence our larger value would allow better optimization of climatechange mitigation policies. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry. Shindell et al.

Historical analysis shows strong acceleration of plantation development in recent years: 70% of all industrial plantations have been established since 2000 and only 4% of the current plantation area existed in 1990. Tropical peatlands cover more than 25 Mha in Southeast Asia and are estimated to contain around 70 Gt of carbon.
Finding meaningful solutions to address climatechange is going to take everyone—governments, companies and academia—working together. The company has spent more than $9 billion since 2000 developing and deploying lower-emissions energy solutions.

Before any licences are awarded, the UK Department of Energy and ClimateChange (DECC) will carry out a screening exercise on the areas applied for, to assess whether the activities likely to result from the issue of oil and gas licences will have significant effects on any protected nature conservation sites (called “Natura 2000 sites”).
The US Energy Information Administration (EIA) has released a new report, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010.

This incongruity provides evidence of human influences on climatechange, says Kaufman. The 2000-year reconstruction of Arctic temperatures provided by the study incorporated three types of field-based data, each of which captured the response of a different component of the Arctic's climate system to changes in temperature.
Nevertheless climatechange is a global challenge we simply have to meet head on. Faam – JOLLY 2000. Cars and vans are absolutely central to people’s lives—it’s how most of us get around and for many journeys they are, and will remain, the only practical and convenient travel choice. It cannot be ignored or side-stepped.
Even under the harshest drying caused by climatechange, the large storage capacity of reservoirs on the Colorado might help sustain water supply for a few decades. entered the drought in 2000 with the reservoirs at approximately 95% of capacity.
